An objective to develop a labor protection engineering stand was set forth as part of the research and development work "Carrying out theoretical and experimental investigations and development of stands for demonstrating the danger of electric shock at a training ground" for visually demonstrating the danger of injuring a person by touch and step voltages in 3…35 kV medium voltage electric networks. The technical solutions for practically implementing the stand were adopted based on an analysis of regulatory documents, conditions under which dangerous touch and step voltages occur, the most typical human injury cases, and calculation results. Specialists of the National Research University Moscow Power Engineering Institute Department of High Voltage Engineering and Electrophysics, working jointly with specialists of PJSC Rosseti Moscow Region have developed, manufactured, tested, and put into operation a stand for demonstrating human injury by the touch and step voltages when a 10 kV wire falls on the ground, on a car, and when a fault of a live wire on the overhead line support occurs. With the stand having been put in use at the PJSC Rosseti Moscow Region Training Center Ground, this will allow the staff to form a clear understanding of the electric shock danger, to focus on the effects caused by voltage and current, and thereby significantly reduce electrical injuries.

Abstract Carpenter 430FR Solenoid Quality stainless steel is a ferritic chromium-iron alloy developed especially for A.C. and D.C. magnetic circuit applications such as solenoid valve core components and electromagnetic relay cores. The electrical resistivity of 430FR is approximately 25% higher than other commercially available 430F stainless. Increased electrical resistivity provides better performance of magnetic components, particularly at power frequencies and high magnetic flux density. This datasheet provides information on composition, physical properties, and hardness. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SS-337. Producer or source: Carpenter.
